Welcome to SAU -
Did you mean they wanted $24,500? instead of $4,500? also I wouldn't personally say the 33 is more capable than the 34 but personal preference prevails.
Given the steady rise of 34/32's the $30k mark will get your foot in to the basics with Series 3's commanding more $ (not a bcnr33 owner myself so I don't have the specifics on models as others)
Lots of other costs to consider apart from purchasing the vehicle - good to see you've started to tally them up
