Yes there are some decent 2nd hand cars. Bit pricey but as Stewart says they do hold value very well.

I've come to the conclusion that, for me personally, buying new is the optimum strategy for a number of reasons.
Well unless I can buy something I know from a person I trust implicitly.

Another alternative is to buy something really cheap just for fun, a couple of weeks ago I was offerered a 6 seater Jeep for P25K. It was running well and had good tyres.
Gawd knows how it got maintained. When I looked it over it had home crafted bits and pieces all over. Including SM bottle tops
I didn't take it based on advice from my wife as it was open style with no aircon.

I'm still not ready to make that leap just yet as the local jeepney transport is just too convenient and cheap.
Even air-con taxi isn't expensive. The average fare for us from home to almost anywhere in the Davao area is less than P120

I'm sure that one of these days we'll feel the need to buy our own transport, but so far no need at all.
