I envy you!!!!
I had an '89 park avenue which is the same as an '88 basically. I loved that car and regretted selling it. The car is super reliable. It has the famous 3800 engine! It is incredibly fast! So comfortable. Mine was white outside and the interior was red leather. I bought it at 145,000 miles from a car dealership for $1,500 and then sold it at 212,000 miles, this was seven years ago---the only problem i had was it need a new blower motor for the heater which cost me $150 parts and labor. I then bought a 1992 buick park avenue and i did not like it like my other one.
I recently tried to find an 1988-1990 buick park avenue (the best years) but could not find one for sale, so now i drive a damn honda civic.
True, american cars suck and repairs on any car are costly, but this particular year buick park avenue and just a few other american cars are an exception. I know cars in and out. I'd pay $1,500 for that car, but i have to see its condition....hopefully its not junked out.
You are lucky to have that car!!!! I want it!!!!!!!!!!!!!!!!!!! NOT REALLY BAD ON GAS!
