Best " year " for the V20

With interest in this boat, was there a " best " time period of production ?

Meaning, since the original model was launched, did Wellcraft make any improvements over the years leading up to the last production year of 96 ?

Likewise, was quality any lower during any of the years ?

Were the transoms all the same in terms of water intrusion, tanks, hull, fit, finish etc.

I'm a new member to this site, and I like it !
Thanks
