Should I Repair My Car or Buy A New One?

car-salesman

As your car ages, it will no doubt need more repair work. So the question often becomes should you get a new car or continue to repair you current one?  With more cars passing the 100,000 mile mark and recent gas price declines, more and more people are opting for keeping their current car.

Before you start test driving that brand new model consider the following:

Can You Afford To Set Aside 15%-20% of Your Income?

  • A general rule of thumb is to not spend more than 15%-20% of your net income on a car. This includes not only your monthly payment, but also take into consideration repairs, maintenance, and insurance
  • Do you really want that chunk of money coming out of your monthly funds? Consider saving that money towards your next car and you could have a decent down payment and avoid those high finance charges when you do decide to buy.
  • If you still find you need additional insight visit this calculator from Allstate to help you with your decision.

Do You Keep Up on Routine Maintenance?

  • A lot comes down to car maintenance. If you diligently follow the manufacturer’s maintenance schedule the vehicle will be in good shape way into the 6 figure mark. The problem is most people disregard the scheduled maintenance and the minor issues can quickly turn into catastrophic problems and easily cost double to fix.
  • It’s often less costly to repair an existing car rather than replacing it with a new vehicle. Look at it this way – a $500/month car payment will cost you $6000 per year added to which you may still need to buy tires and some routine maintenance.  Well timed repairs and routine maintenance will likely be considerably less than $6000 per year!
  • European cars tend to be more expensive to buy initially, however, they generally keep their value better in the long term.  In addition, many European models are designed to well exceed the 100K mile marker.  Good maintenance has helped many of our customers exceed 200K and even 300K miles some cases.

Don’t Forget – Higher Insurance & Registration Fees

  • Don’t forget those taxes and fees you have to pay in addition to the sticker price of a new car. New cars generally require higher insurance fees to cover pricier repairs in the event of an accident.
  • As a general rule, foreign brands are more costly to insure and repairing them generally tends to be pricier.

The Rate of Car Depreciation is Insane!

  • On average, a car depreciates the most after one year of ownership and continues to depreciate at a rate of 10% each year thereafter for the first five years, according to Consumer Reports. See the chart below:

There are many things to consider when you are looking at buying new vs. keeping your current vehicle. Generally, if your vehicle is paid off and your annual repair fees don’t outweigh the cost of a monthly payment it’s best to keep your current car and save the money for a full cash payment on your next vehicle. Also, it’s important to find a reliable and trusted mechanic like Rennology Motor Sport.  We let you know of your vehicles problems and give you the best solution for you and your wallet!

Why Is My Car Overheating?

Overheating is the most common cause of roadside breakdowns. With temps hitting the mid 80’s in Chicago it’s more important than ever to make sure your vehicle is in peak condition for the upcoming summer months. In this article, we share what to do if you end up in a situation where your car is overheating and also tips on what to look out for.

overheating-car-roadside

What to Do if Your Car Overheats:

  • Turn your heater or A/C to the maximum – this allows the car to cool down by dispersing the heat in the engine.
  • If you happen to be in heavy traffic, shift the car into neutral – this draws more air and liquid through the radiator to help cool things off.
  • It’s best to pull over to the side of the road and let your engine cool down. Major damage can occur when a car is overheating.

Most Importantly…

DO NOT open the hood until the engine stops steaming and cools down.

DO NOT open the radiator cap while the radiator is hot.

DO NOT add coolant or water to the radiator when the radiator is hot.

Reasons Your Car is Overheating:

Low Coolant Levels

  • This is the first thing to check since it is the most common reason. If it appears low you can refill the coolant, but if you are entirely out of coolant it may be best to tow the car.

Coolant Fan Failure

  • Is the fan acting sluggish or not working at all? This could be due to a bad electric fan or bad radiator fan switch.

Cooling System Leak

  • Check underneath the car to see if you notice any liquid. If so, you should take it to your mechanic to have them pressure-test the cooling system.

Thermostat Malfunction

  • The thermostat needs to open in order to keep coolant flowing through. This is most crucial on hot summer highway drives.

Clogged Radiator

  • Flushing your radiator is recommended every couple years so it’s in peak condition.

Water Pump Bearing Failure

  • Bearings eventually wear out due to the constant load from the drive belt or timing belt.

Check out this great video that explains how the engine cooling system works.

You can easily prevent overheating by checking your liquid levels in the vehicle’s system and maintaining it correctly. We don’t want to see you stranded on the side of the highway this summer. Call Rennology Motor Sport at 708-687-5258 is you are experiencing similar issues with your European vehicle.

Carbon Build-Up In Your Engine

Our shop sees many cars with direct injection engines that have carbon build-up on the intake valves. Most recently we had this BMW 335i in our North Aurora Shop. Check out the before and after photos of the intake valves!

Before

After
                                                                                  bmw-carbon-build-up-after-rennology

Carbon build-up is very common on engines that have direct gasoline injection systems. The carbon build-up is an end result of crankcase vapors (dirty leftovers from the combustion process) which also contains tiny engine oil drops. The dirty crankcase vapors cannot be allowed to escape into the atmosphere so they are routed to the intake manifold to be burned with the air fuel mixture and then further treated by the catalytic converter in the exhaust system. The vapors/oil mixture is supposed to be separated (oil separated from the vapors) prior to entering the intake manifold, but apparently this part doesn’t function very well or is a poor design.

The check engine light will turn on, the engine will run poorly at idle (due to air restriction), and there will be misfire faults for each cylinder in the engine control module. Note that installing fuel additive into the tank will NOT help. A very common scam is for auto repair shops to sell a fuel injection cleaning service as a fix for this but in truth it will not even remotely address the issue.

Aftermarket suppliers have designed a system that collects the vapors/oily mixture and directs them to a separate canister instead of the intake manifold. The only disadvantage is that the collection cylinder needs to be manually drained frequently and is not emission compliant.

Regular servicing can help catch and prevent this issue before you end up with a large repair bill. At Rennology Motor Sport, we specialize in engine carbon cleaning for Audi, BMW, Mini Cooper, and VW. Carbon cleaning can be completed in one day and returns engine performance to near new levels.  We offer two convenient locations in Oak Forest and North Aurora.
