billy, $4600 buys a heap of petrol. also factor in the interest on that $4600 (if you're borrowing the money). work out your hours of use for the year and figure out if it's worth it for you to spend the extra money. there'll be a "crossover point" where if you do enough hours per year the extra expense in purchase price and servicing will be paid for by the fuel savings. good luck with your decision mate
