Here's a short summary I posted in the Facebook group a couple days ago. This is a summary of highs I've observed for stock-ish ZR-1s:
The '93 for $86k is the highest I've seen.
Off the top of my head, the other significant ones:
- BaT black '95 with 145 miles sold for $71,500 and is now for sale at a dealership in CA for $85k (make that $79,900 - price just dropped...)
- BaT green/saddle '90 with 400 miles sold for $73k
- BaT quasar blue '90 with 1,100 miles sold for $60.6k (I think), and the secondaries were noted as not working.
- BaT black '95 with 2,200 miles sold for $51k or so.
- BaT '95 black with Dunn heads, 819 miles sold for $50k in August
- BaT 11k '95 sold for $43k with minor mods
Outside of BaT there were the three no-mile black ones ('90, '92, '94) from Mecum in January. I believe the sale prices on those were $66k, $5xk?, and the '94 with 29 miles sold for $82k. All three are now for sale at the same California dealership for $125k, $115k, and $125k, respectively.
- A '91 quasar blue from the same collection with 4k miles sold for either $51k or $56k at Mecum.
- Marty at Contes recently had a '95 blue/black - I think it was just sub 10k miles (?) asking price was $70k and it went very quickly, under a week.
- Two weeks ago there was a '94 blue/black 19k miles on eBay with BIN $46k, sold for just under $45k with two bids.
These are the highest I'm aware of. These were all stock or near stock. Nice, no- to low-mile cars are bringing good money.
I also have seen this site, which is a pretty good record of ZR-1s (and other classics) sold.
