In reply to iusedtoclimb:
Everybody has their own risk/reward and tolerance to costs and embuggerment on this topic.
For me the best balance of economy vs relatively low hassle if moderately lucky is to buy nearly new and keep a long time. You generally get full remaining warranty (especially if using manufacturers approved schemes etc) and you can either buy outright, lease or PCP the car.
Last one I bought was a 9 month old 6,000 miler, nice price vs new, the manufacturers incentive scheme at the time (VW) was offering me a £2,000 deposit contribution and 2 free services if I took finance (which I was lucky enough not to need) - so I took the finance and exercised my right to withdraw on the day I collected the car and paid it off, less their deposit which one is allowed to keep. But If I had needed finance it would have taken the sting out of it a bit. Keep an eye on these deals as I saw the deposit contribution go from £2000 down to £500 and back up to £2000 on the model I bought over a few weeks so sometimes you get lucky, sometimes less so depending on whatever is going on behind the scenes to generate sales/what stock levels are like etc.
It might be cheaper to negotiate hard on the car and pay for it via a bank loan as bank loans are at present a good bit cheaper than most motor finance interest rates. Actually - I'm sure one could use their finance to get deposit contribution and then use a cheaper bank loan to pay the balance off... sneaky. The trade in they offered was poor (bit of an obscure car I was selling though) so we struck deal based on their trade in and I then said I'd collect new car (was coming from central stock anyway so bit of delay) within 3 weeks max and would try to sell privately which I did for double their trade in so again, I won out for a little work. It was a zero risk as if I didn't sell at a better price they would still accept the trade in.
If I've had the car from virtually new and look after it I recon on trouble free first 5 years bar consumables then 3 to 5 more reasonable years. I save the same every month towards running costs so generally build up a pot in first few years that then gets smaller as a few larger repair bills crop up in second half of ownership.
In my opinion its far easier to run a car for a long time and into high miles if you know its history and who has been driving it. i.e. me.... I've been caught out a lot more buying 3 to 6 year olds than I have nearly new or oddly very old. I think a good banger is easy to find/spot vs a bad banger... however a 5-7 year old car looks respectable but could have been badly abused and have a ton of stuff ready to go that is harder to spot as otherwise it still all looks and feels ok... that same car will be a ragged dog in another few years and easy to spot vs the biddy owned, well looked after 10 year old.
All this is driven by me being tight and hating the thought of paying top dollar for a depreciating asset that somebody will no doubt whang a trolley into shortly after you buy it, but wanting reasonable efficiency, security, safety and trouble free ownership. The household has 2 cars and I can get too and from independent garage, home and office reasonably easily by using train and running when I'm getting work done so I'm not in the 'it must work 100% of the time and I can't manage without it for 2 days if it needs an overnight repair' camp.....
