True, but it doesn't mean you have to be silly about it. For example you wouldn't buy an old r00ted fishing boat on a rusty trailer and start fixing it at a cost of $25k when you could buy one ready to go and use today for $15k. I totally get that if the fishing boat was a rare Bathurst model or was a special one with stripes and optioned with a big engine then it might be worth the labour of love.
Just my opinion on such stuff!
