in the market

hi all,
i am new to this forum but need help. i am in the los angeles san bernadino area and am looking to buy a boat. i would like to pay around 20k for this boat. i currrently am looking at a 1998 alpina 20' with a tower the asking price is 21500 i think this is steep and i dont know much about the boat itself. any help would be appreciated.

i would buy an older sport nautigue it has almost the same hull as the SAN and has a killer wake weighted right or check out a supra Sunsport that is a huge hull with lots of wake potential.

thanks maverick, i will look into your suggestions
