Differences between an 1.8MPi and a 1.8VVC

When looking at the powercharts, we notice that the peak power of the VVC is reached at a higher rpm.

From the outside, the differences between an Mk1 MPi and VVC are the following:
* Have a look at the wheels:
        MPI: 6-spoke wheels,
        VVC: 5-spoke wheels
(see Wheels section). This is a difference when speaking about the MkI, as from modelyear 2000, the VVC had standard 16 inch 6 square spokes wheels, but those were many times fitted as an option on the MPi. Wheels from the VVC will fit on an MPi and vice versa.
* On the revcounter of the dashboard:
        MPi: red line starts at 6750rpm
        VVC: red line starts at 7250rpm.
* The VVC comes with at least part of the seats in leather. Full leather seats are an option on both: MPi and VVC.
* Most accurate: the 8th letter of the Vehicle Identification Number (found on a small plate at the base of the windscreen):
        G: MPi
        T:  VVC

And ...
* When opening the boot and peeking into the engine bay, you will notice the silver letters VVC on the plenum chamber.
* In most of the countries, the VVC comes standard with ABS (unit can be found under the front bonnet) while it is an option on the MPi.
