It must be a Tiico thing, the buzzy 4 syndrome.  The one I have, a stock
cabriolet 1.8 liter, is not buzzy at all.  In fact, I have always wondered
where that perception came from.  I have not ridden or driven a Tiico, but
my standard VW is as quiet as a "mouse".  Yah, you have to wind the pi** out
of it to make any speed, but what the heck can you expect when you're moving
a 4000lb, 6' tall shoebox down the road at 70-80mph with less than two
liters of displacement?  I bet if you stuck a 3 liter 968 Porsche inline 4
in there, you would probably perceive it to be just "loafing along" (no
pun?)
  Someone should stick two hardly Davidson "motors" into a van...How cool
would that be?  You could have a little more horsepower than a stock van,
but you could make it really LOUD and maybe dress up in a leather leisure
suit to drive it..
 friday, don'tcha know.
