Legit way... people are still farming RR like there is no tomorrow.
i havent played not one of the new missions since all i get are RR invites.
"Legit" way... the car duping/selling glitch is in full swing, im waiting for a reliable solo method. as well as the easy sp2mp method made it return to xbox with patch 1.13
Yeah, the way with the mule is so unreliable. I get it to work 1 out of 10 times. I had it going good for about 500k worth, but I think the mule moved a bit and messed up my line. Also, when I tried it after logging off for awhile, it doesn't dupe my bike when I go flying off..not sure why. Anyway, it's nice to do solo because with the Thrust, with all the best upgrades excluding engine, transmission, and turbo, you get 97k. No need to do the insurance glitch with a partner to increase the value because 100k in 5 minutes beats RR any day.
Aside from that, the crime scene mission from Lester is fun. Lots of gunning in that one. The Handle With Care mission from Madrazo is absolutely ridiculous. Took me well over a half an hour to solo it, for $10500 and 1950 RP. And the other Madrazo mission, "On The List" is 15 minutes of driving for 8-10k. They must be cash card hungry because all these new missions for this so called High Life update are chump change in relation to the new items they offer.
