JC Taylor worked well for me, my father and I have had several old toys registered with them... I'm classically challenged at the moment lol (sold everything to move back up here).
No mileage limit, must be garaged, and couldn't be the primary vehicle. I got around that with company cars and DDs, I've always had something late model around.
The most recent examples I have are before I moved back to Alaska in 2017, rates for reference were in Maryville, TN 37804.
1970 Camaro agreed value $25k
1965 Impala agreed value $10k
1972 C10 agreed value $7500
Total annual policy cost $325... stupid cheap. For comparison the 2004 Suburban 2500 and 1998 C1500 with Allstate at the time were over $900 a year.
This was with a multi line discount and paid in full annually. They required pictures of the vehicles and pictures of the "locked indoor storage location." No appraisals or other information needed. I enjoyed my JC Taylor experience from 2003-2017 and if I end up with another antique/classic/hot rod they'll be my first call.
