The other reviews here are penny ante, very minor stuff.
The other reviews here are penny ante, very minor stuff. I asked Lisandro for an out the door price and I got it fast, with options to help me with financing and shipping. Most other dealers are very slow and never give that price. Performance Mitsubishi's price was $12000 more than advertised. Give both a chance and you will do business with Lisandro. Spend a couple minutes and see. Besides being GREAT to deal with, test drive the Outlander. It drives better than the Rogue and is crazy cheaper than Toyota. It is nicer inside too. Don't buy a turbo gas car. They don't last as long. Buy an Outlander from Lisandro and you will get the deal and be happy with your car.

Good experience
Recently I started a hunt for vehicle something I dread doing but I had a pleasurable experience this time. I came to Schumacher Okkachobee and was assisted by Johny Chacon who found not one but three cars to choose from. He was very knowledgeable about vehicle's information. The manager was very nice and did not hard sell me which made me run out of other dealership down the road. I was very pleased with my sales consultant Johny Chacon who found awesome vehicles that would meet all my needs. My first stop was at sister store close by my home very first vehicle to look at, I was love bitten. So that became my choice but I really felt the need to give Johny Chacon an excellent review for all the help and assistance he gave to me while I was investigating my options. 5 star assistance.

Response to my inquiry was prompt and courteous.
Response to my inquiry was prompt and courteous. So was the follow-up as the sales agent checked with me regularly. The initial internet presentation of the car wasn't great as pictures were of "other" cars of the wrong color, etc. I didn't buy the car so I don't know what happened after a few days.
