It's near new car time and I can't decide, so any input is helpfull. I love the v8 sound and feel like it's a more mature car. But price wise it's at my max unless I can get price down. The a5 is very low right now and I could put integrated engineering block and head in it for about $6500giving me 500 or more hp and tq. Any suggestions on what I should or could do?
