I have had a couple of single turbo supras including Auto and 6 speed, I have also had a stock 6 speed TT, 2 Auto BPU's and an 2 NA's, I stand by the BPU Auto being the best all-rounder for the daily driver, especially if you live in a busy area like me
I have to say though that I miss the big thrill of a high horse power car and the Supra (and skyline) give a lot for very little cash, however this does not mean that owning a single Supra is cheap, you need to be fairly well off IMO to be able to run one and really enjoy it without worrying about the bills it takes to keep it running, Oh and you will always want more power every few months or so !!
I am looking at Nells RX7 Single at the moment as I have always wanted to try one, however if it does not stack up I am spoilt for choice with singles for sale at the moment
