This is a very good question and I too will need to decide this in nearly 3 years time when the warranty runs out on the 200. What with the issues with the Recaro's, I probably should extend. If after 3 years the seats have caused me that much hassle and i've still got the car when out of warrenty, I would be tempted to pay for standard seats (as opposed to keep replacing Recaro's)
My 172 has been good, however, I fear the wear a tear on the 197/200's are not brilliant.
Now, where's my crystel-ball?
