Should I purchase this 2003 iS with 101,000?

[RonVF]

Should I purchase or walk?
I am scheduled to purchase a 2003 4.4 iS tonight. Car has no, nav, no Dsp, no winter package which is a big deal here in Upstate NY. Car has 101,000K and it has had 3 owners all from TX. Car is fairly clean and carfax looks good. Price is $4200.00
From what I can tell it is going to need ALL the common items and those I see right away are, valley pan ( coolant was low and drip at rear of engine), RF outer cv boot, water pump ( hasn't been changed yet), right door handle'is broken and won't open the door from outside, left rear window won't stay up. Owner thought it needed a torque converter but after putting a new battery in the transmission is shifting fine. Now the ABS, brake and triangle lights are on and the airbag light is on. Owner of the last 8 years, 60k said only thing he did short of new tires, brakes and oil changes every, was an aux fan for ac.
Car will be for my wife and she is not good about checking gauges warning lights or sounds...
I'm also going to want to put an aftermarket nav/Bluetooth, backup camera system in if I purchase.
Thanks
