Nothing, the car is rock solid and in perfect shape.
Everything still works as original including the clock!
Kept under a standard maintenance plan, this vehicle will still be on the road when many other made today are in junk yards.
I really like this car also, it has massive power and plenty of low end torque. It might use a little gas, but it's worth it.
I just bought one of these to run in a Demolition Derby here in Phoenix AZ. It is such a strong runner I am having second thoughts about the dirty deed.
I also currently own a 1984 Olds Custom Cruiser; paid $75.00 for it last year because a buddy had to remove it from his yard. Has 38,000 thousand actual miles,307 V8 4bbl, and is loaded like a Caddy on options. Just pump the gas pedal twice when cold-starting and it fires right up- unusual for a 21 year old Quadrajet carb! However, the car needs a new transmission, as my aformentioned buddy fried it doing "neutral drops" while drunk one night. Now that I own the car, that and some other age-related issues will be addressed soon, as I only intend to use it for a part-time play toy. An incredibly original car, and I'm glad to own it, instead of it going to the junkyard or a demo-derby!
