Plan is to run it until the new year (latest of March) and then move back to a newer BMW once I've got the money (1-year savings account can't be withdrawn until March without penalty/loss of interest)
How much would you lose in interest/penalties? (Not actually asking you to share personal details/figures, rather raising the point questioning if it's worth waiting for what you really want for the sake of a few quid in interest.)
I realise that the newer BMW becomes cheaper as it'll depreciate further as time goes on, and the bargain(?) purchase price means you might be able to turn a profit, or at least break even, but taking the interest point in isolation (ie, if this Audi was never offered to you) is it worth spending more money running/repairing the 330d, when you could simply bite the bullet and write off the interest and buy what you want?
Interest rates are so low atm that I'd be suprised if the loss of interest was a considerable sum, but I've no idea what other penalties could be levied...
