Not much Opel left in that one. This is what they usually look like:


You know guys, I think that top speed is on the quarter mile... :eusa_thin

Probably the gearing. On older cars like this, it wasn't uncommon to use a 4-speed manual.

Also, the gear ratios are probably low to ensure quicker acceleration at the expense of top speed.
