Listen to your car

Every now and then listen to your car at lower city speeds. Listen for squeaks, squeals, or grinding sounds this occasionally will help prevent small problems from becoming big.

Avoid parking in the direct sun

The sun is the greatest enemy to your car, second only to road salt and disuse. The sun will try out rubber seals, bake off low quality paint, and accelerate exposed component degradation.
