Q1: Can I buy a car for 45-50,000 QR? If yes, what type do you figure. I currencly have a Honda Fit here in Vancouver and was hoping for something similar.

Yes you can...Just look at the classsified section...Recommend SUV cause the roads here suck

Q2: I will have 8000 QR for housing allowance. As I'm single, I was wondering if this is enough to rent a one bedroom (studio) type apartment. I hear the rents are through the roof over there so just wondering if I would be renting on my own or possibly sharing.

Yes you can...I have an apartment in 5 unit villa in a compound...Rate will increase to 7K soon...I think these are hard to find though

Q3: This will sound silly but I'm a very nervous driver and after reading postings on this site, even more so. Is it really suicide to drive over there? If yes, I may change my mind about coming.
Thank you much to all who take the time to read and respond.

Yes it is...But the nervous drivers survive...It's the ones who get pissed off like me that have the problems...I've got to learn to quit chasing down the a holes and never mind....And alot of it depends where in town you have to drive...Some places are much more tame than others...The industrial area is the biggest challenge....And I unfortunatly have to tackle it 5 days a week

Welcome to Qatar...

Sincerely,
Jeff
