The speedster was built prior to 2013 by Vintage Speedsters (Kirk and Mary era). Prior to 2013, Vintage Speedsters (VS) used to use a curly-q alternator wire. In addition, they had a single centralized pocket on each door card. 2013 and beyond, VS moved to a map pocket covering the entire lower section of the door card; and stopped using the curly-q wire.
This car looks well maintained. It does have 4-lug wheels, as opposed to 5-lug (given the age we could tell by counting the ovals in the wheels--8, which is 4 lug, as opposed to 10, which is 5-lug). Newer wheels can do 8 or 10 openings with 4-lug.
Here is where some assumptions come. VS did a lot of 1600cc and 1915cc engines. In addition, they did disc brakes up front and drums in back, or 4-wheel disc.
This car is a minimum of 14 years old. It is well taken care of, by the photos, but still 14+ years old. Which can either be good (or bad). If you're purchasing a car from someone on this forum, chances are they love their speedster or Spyder more than one of their children. The slightest thing off has been chased down and repaired, to the point where a 14 y/o speedster (or Spyder) may be better than one delivered new. Or a 14 y/o car may have rattles and such that will drive you nuts, because the owner drives it 50 miles a year and couldn't care less.
That said, there will be some commonalities. Such as driving position. Whether a 14 y/o VS or a new Vintage Motorcar or a beck, you will pretty much be sitting in a similar position as it relates to the street and the cars surrounding you. BECK Owners, are the footwells the same as VMC and VS?
Also, overall driving experience will be similar in that these are raw cars. The wind will hit your face the same way in a VS, Beck or VMC. The engine noise will be similar. The comfort (or lack of comfort) will be very similar.
There are a number of fine tuning differences between VS, VMC and Beck. Quality differences too. But looking at it 50,000 feet up, this rental should provide you a good impression of whether or not you want to pursue buying one.
