The 88's are somewhat coveted due to them being the only year where certain suspension improvements were available.
Common things to watch out for when shopping are...
- the rusties having taken their toll on the frame rails above & behind the rear wheel wells
- damage to the coolant tubes behind the rocker panels due to improper lifting
Beyond that... simply remember that you're looking at a 16-20 year old car which will have any number of problems due to age, previous owner abuse/neglect, etc.
