Renting a car in Udon Thani, Thailand.

Hi all.

Me and my family are coming to Udon Thani, Ban Dung on our family visit trip.

We are not going with the big name companies like Avis or Budget in Udon Thani airport because we wanted to pay the rental in cash and the big name companies only accept credit card.
We have been comparing rental cars in udon thani and stumbled upon UD Car Rent https://www.ud-carrent.com and Lek Car Remt and we were wondering if anyone here have had any experience with these 2 companies?
UD Car Rent does seems to offer a fair service with lots of positive reviews on internet, any ideas?

Thanks
// Mick.

I used Lek about 5 years ago and they were good. They were okay to pick up at airport and hand back at the hotel. No problems with paying cash then either.
