parents are getting older too, they dont like being reminded of their mortality and perhaps they bawk at the idea of a brand-new car, maybe a 1-2-3 year old car is what they are thinking of, the idea is that, for say you own the next car for 5 years, each years you owned it is 'split by 5 years of the amount you paid- $24,000 (but make it 25,000 for that easier to grasp of the maths example here ok?)' of that 5 years, you work it out as $5,000 per year just to own it.
Now, then put this next to a lightly-used car, do the same maths you're looking at like say $15,000 for it. Own it for 5 years, would work out as $3,000 per year ok
then consider each year you saved $2,000, for 5 years that amounts to $10,000 in your pocket.
I would bet you that by 2 years down the track that brand new car feels just like another car, while the lightly used one is gonna feel the same at 3 years, except you would save 10 GRAND.
It is well known that as soon as you got the car out the door brand-new (say 25,000) you effectively have lost $5,000 immediately for the the privelege of being the first owner, then 6 months down another $5,000 is gone, that's effectively $10,000 'gone' already you wont get it back, whereas the used car... you lose alot less and there is a chance to sell it later for a modest return but it will still never be at the level as a 'refund' unless its called a Ferrari or similar...(those top-grade sports cars costs thousands to run, not just the gas, i wont mention it here but lets say a fanbelt change would send you back at a minimum of $2,000 easy...)
So there, its all comes down to what you want to do, be the first owner of the car, (tune ups are great, it brings the performance right up- unreal- but i guess that depends on what it is)then again a very lightly used car will give you pretty much the SAME enjoyment, even the tuneups if the warrenty is transferrable and 'extended' somewhat. That's more homework for you to do too, if you really want to know what's the BEST deal you can get...
over to you, and good luck and dont tail-gate (driving too close to the back of the car in front of you) so this kind of prang wont happen again (which as you found out, is a bloody big nuisence).
