test driving 07 yaris on Sun, quick questions

[rickc]

Hi Yall, I know it's not good etiquette to ask questions without reading every single post in a forum to see if it's answered but i just dont have time. If anyone can answer these ez questions i would appreciate it!

I drive 40,000km a year and need to upgrade my 2002 focus which just hit 200,000 kms and is falling apart (air cond just broke latest issue). so i'm looking at a 2007 yaris as a replacement.

1. Is it comfortable for long trips? if no can it be easily made more comfy? i already found a center armrest on ebay so im more concerned about the seat - i'm 5'10 and 200 lbs.

2. is it fairly easy to add aftermarket cruise control? this one is a manual 5 spd so i am aware of the safety issues involved.

3. i've read the body roll is considerable when cornering this car - any suspension upgrades/mods ppl have had good results with?

thanks!
