I know they used to be as long as they were Buick powered (3800 Regal, LeSabre, Park Avenue, etc) but now that they’re all corporate I dunno. Patrick
I would sure want to read my rental agreement, some companies track their rentals, plus if something happened it could get really expensive really quickly. Is someone that desperate to race?
I would discourage it.....somebody will let the rental company know and your friend may be disappointed when they go to pay the bill......the car would stand out like a sore thumb..... Peace WildBill
