I would say it's a scam, my best friend here in La. is a state fraud investigator for the AG's office, and at this time they have 3 on the table from Sweden and Denmark and these are from car dealers who got screwed here.
IMO, i would have his friend from Westlake bring you the cash and then it's off your plate. I would not give him your banking imformation, and with Paypal he can claim a bad deal and you cold get screwed.
I've been a member of PayPal for 8 yrs. and use them all the time,i have respect for them but they are buyer orientated.
PS, most people in Sweden, speak English but with an accent.
