repayments v running costs
The purchase v resale argument has a bit of a flaw in that yes you pay more for the diesel but you should also be able to sell it for more when time's up.
Using the floated $5000 difference in purchasing cost, the diesel should cost you less than an extra $30 over the V8 per week in repayments.
Bet you save more than that in fuel a week! As already discussed the maintenance costs are similar.
BUT as said before, which one do you want. Your either a diesel man or a V8 man!!!!!!!!
