Interesting one...
Until November last year when I bought my brand new MIA Precision I had never bought a "new" guitar. This was probably down to all my heroes playing guitars that arent necessarily on the beaten track, or arent even made anymore (Jack Bruce, Cliff Burton). So I would say I like both, it was a lovely feeling to buy and own a bass that was purely mine (and always will be because its awesome) but im equally happy buying something with dings and belt rash if it plays and sounds the business. Buying from a reputable dealer also helps.
I would point out that I dont dig the "reliced" look when it isnt actual real "relic wear" though... some of those Fenders look pretty convincing but compare it to something like

and they just dont convince.
