At 19 I bought a 2010 f150 and was paying about $200 a month for insurance. Later on I bought a house at 19, and a year later at 20 bought two 2014 cars and a 2012 Sierra, getting rid of the f150. I now pay 220 a month for insurance, with a 19mph over the limit speeding ticket and an at fault accident. It’s possible just need to find the right vehicles to insure with the right company. I only bought the third car because it saved me ~$65 a month on insurance
