CV axle joints went bad around 93,000 miles.
Muffler keeps rusting out (the small engine does not get hot enough to evaporate the water in the muffler). I am on my 3rd one and am thankful for Tuffy's Lifetime Warranty :-)
Exhaust pipes rusted in numerous places between 135,000 and 140,000 miles.
The front brakes have given me problems, but not more than any other car I have previously owned.
The proper tire size (R12/145 - not 155) are hard to find.
Rust on the engine and undercarriage is quite rampant.
I love the gas mileage in this time of high fuel costs (34-38 miles per gallon).
Parking spaces are easy to find and/or make.
It does not like cold mornings. My advice is to keep it in a garage if you live in the Arctic north (Ohio).
I have owned my '91 Festiva L for over three years, and never ever had problems starting it in our Montana winters, where 20 below is not uncommon.
I am looking to buy a 1990 festiva for $400canadian. I hope it starts in cold days because I'm from Northern Ontario, where -30degrees Celcius IS common. BRRRR!!!
