New to Hyundai...question on 02 Sonata
 

Just bought an 02 Sonata with the 4 cyl auto...fully loaded except
leather and heated mirrors.
The timing belt was just done and all fluids were changed out. Car was
motor vehicle inspected 2 weeks ago...Car has 90,000 kms...60,000 miles
What work should I look to do?
Any major issues with these cars?
Any sites for stuff like headers, intake, exhaust? Or is it worth the
effort to upgrade?
