I don't know. The Vette is killin me on Insurance and Tires and Taxes. The HCH will save me a little money in gas and tires even if I keep the Vette. The only way to make the whole thing pay off is to say bye bye to the Vette. If I sell the Vette within 45 days of buying the HCH I save sales tax as well. It would be stupid to keep it but that doesn't mean I won't keep it. For all its flaws it is still quite a car, one that has never been wrecked and runs/drives perfect.

By getting rid if it I'd save $1200 in sales tax, $50 a month on insurance (compared to HCH), $70 a month in tires, $42 in gas (at $2.00 a gallon) and actually nothing on personal property tax because the new HCH is worth about the same as the used Vette.

By keeping it I'd loose the $1200 deduction in sales tax, have to come up with $100 extra a month in insurance for the Vette plus $50 for the HCH for a total of $100 a month extra over trading the Vette. It would cost about $35 extra a month in personal property tax to keep both cars. Assuming Vette usage is cut in half the extra cost of tires of both over just the HCH would be about $35 a month. Gas would be $21 a month for both over driving just the HCH.

Grand total $1200 plus $191 per month to keep the Vette.
