The fact is innovation and technology is mean't to lead to the constant evolution of a product - The only evolution thats taking place is the price and the fact that they decided to skimp on every conceivable extra given as standard in the 172/182, which is partly what made them such good value.
The 197 is slow, it's heavy, it's bigger than a 52 seater coach, and the back end has been designed by a 5 years old with a crayon, the fact they come off the assembly line in 4x4 monster truck mode also doesn't help them hide the fact that because the car is so overly inflated the wheels look poxy!
For Xenons and everything else you're looking at the best part of £18,000 which as has been discussed pitches it against cars that will wipe the 197 from the equation.
As a 172 owner, spending out £18k on a car that's going to depreciate like fury is a no brainer, the fact they're also not selling well means that eventually dealer prices are going to drop, importers are going to undercut them and soon enough they'll be a Meggy situation where you just can't sell them without loosing 10k.
I'll keep the old rattle, driving position (fine for me tbh), and my money and keep the better car.
The car is a half arsed effort with too much thought into displacing the Meggy from the range, which given their s**t sales means they've sacrificed the 197 to avoid cutting it's sales further more IMO.
