Hello all. I just recently purchased a one owner fully loaded 1997 Riviera with 147,000 miles on the odometer. So far I've changed all the fluids, replaced the tires, and tinted the windows. The plan is to keep it stock mechanically, tighten up any issues and make this a nice weekend cruiser. I think I may have gotten Buick fever because a few months ago I picked up a one owner 2007 Buick Lucerne (white diamond with tan interior) with 149K on the clock. So far I'm loving the 3800 V6 and now that I have a supercharged 3800 it's even more fun behind the wheel.
One thing I just noticed on the Riviera is the back of the engine rises up when switching from park to drive so I think the transmission mount is bad. This wouldn't suprise me because I had to replace two engine mounts on the Lucerne when I first bought it. The mounts on the Lucerne were very easy fixes with a jack and a few tools. The Riv also has a slight oil leak which I need to track down and fix as well. Hoping both of these are easy fixes on the pocket book.
Anyway, I've admired the Rivieras since they were first introduced in 1995 and I'm glad to have finally picked one up 25 years later. On another note my brother has a 1997 white/burgundy Riviera which is currently sitting in his garage (Rust Belt) due to a rusted sub frame. Everything else on the car is in good condition so I may buy it and use it for spare parts if needed. I'll be searching this board for the wealth of knowledge so many others have contributed.
