NICE! I had the identical vehicle back in 2003. I bought a yellow 2002 ZR2 in October of 2003 for $12,000 with 12,000 miles. I only kept it a month before trading it for a 4 door sedan. I had a kid on the way and was having second thoughts. I have regretted it ever since. Whenever I see a ZR2 I miss mine.
As far as tires I'd recommend the BFG All Terrains very highly. I had them on my Wrangler and they were great in snow and pretty good offroad. Plus they look great.
