Hi dblarrel, it's been a long time since we've heard from you, glad to see you still kicking around
We have a few tours lined up for this year, if you would like, PM me, and I'll add you to the list.
I believe you meant say a XJS with Chevy in it. That very well may be (In 2022) We're talking 1991 when I was looking for the wife's Jag. We did find a beautiful 1984 1-owner Cobalt Blue with Fawn interior.
A lot of things (Rules) have changed since then, "Sovern" our vintage race club when I joined (1993) the cutoff date for production cars was 1969, and Formula/Sportracing 1972, now it's 'run what you brung' Cheers Tom.
