First of all, hello to everyone here. I am lucky to have stumbled on this website while searching for diecast models. I am new to the hobby and would like some advice. I would like to have a small collection of about a dozen cars. I won't get into specific models but in general porsche, ferrari, lamborghini, etc. I noticed there is quite a price range between 1:18 and 1:24. I was wondering if people thought the difference is size was worth the price difference. Also, are cars in general more harder to find in 1:24 than 1:18? I can't find an red mazda rx8 in 1:24 anywhere. I also was curious about the quality of maisto models which are cheaper than than the autoart (which I'm presuming is good quality). Thanks.
