A new investigation has shown that the purchase of UK car and automobile spare parts in 2017 was the main complaint by Irish consumers.
Most of the complaints related to defective second-hand cars, guarantees, and problems with deposits.
The study was conducted by the European Consumer Center in Dublin and the Consumer Council of Northern Ireland.
Martina No. of ECC Ireland says that Irish consumers had a lot of problems with buying cars in the United Kingdom.
"You had complaints from Irish consumers about traders in the UK when they bought cars, mostly used cars," she said.
"These kinds of complaints were about guarantees, logs are not provided.
"There were also problems with car parts, they are not as described or they are not correct or there are problems with their delivery."
