Hi Gary and welcome to the club.
I've had my 2.7 se for about 18 months now and it's never let me down.
Having said that it's had a new battery and heater control valve.
Your Must haves shouldn't be a problem mines got parking sensors front and back , heated seats , fold back mirrors, cruise control, memory seats and steering wheel. The foot peddles also can be electronicly adjusted.
Things to look out for are ,
Sills corroded, water in boot ( that's where the battery is ) Cambelt replaced if over 105,000 miles, smooth gear changes if auto, heater working as it should and check on the government mot history Web site to make sure there are no nasty surprises waiting to appear.
If you choose to purchase the car you won't look back because they are a pleasure to drive and you will go everywhere with a smile on your face.
Gary.
