I found a Corolla GLI 1994 stock condition .. used as commuter car from house to office .. The exterior is still in good condition, still in original paint not washover .. interior is good also ..

Given the age of the car (1994) of 21 years already and being an EFI engine, what are the common problems of cars this old ??? How to know if such problems are present ??

What are the problems of the EFI engine when the car is 20 years old ???

Baka kasi sasakit ang ulo ko kung maraming problema in the future ??
