I don't really believe in putting in much of a deposit, maybe £1k if they insist. Some manufacturers and independents do allow much higher percentages these days.
The TE has been discussed before, bit of mixed bag. Could have done a rear seat delete, maybe some more power and as a 'Track' car, I don't think it would hold up well, plus if you do ding it, £££ bills I'd imagine.
However, considering the F range is an infant compared to other cars M, AMG etc lines, bravo for them giving it a go. If money allowed and as an enthusiast, I would have one for sure.
Launch control might help....maybe 😆
